I was searching for a way to make a simple midi controller and I found this video , its exactly what I want but it uses a midi jack which requires a midi input , I researched more and I found that this is unnecessary in some arduino versions but I basically have no idea how to approach making this modification , does anybody have experience in adruino can point me to the right direction ?

 

Not what you asked, but there are USB to MIDI adapters that you can probably use to save you they headache of trying to integrate midi directly. I use one on a mackie controller.

 

I thought about it but the problem is in addition to having an extra usb connection it requires two softwares to run in the background which is a pain to setup

 

I don't understand what you're trying to do - you want to use this gizmo to send midi signals to something but you don't want to use a midi port or a usb connection?
What sort of connection are you intending to use? What do you intend to connect it to?

 

I made a guitar pedal using A Arduino uno some Stomp switches and 2 pentos for pedals, cost around 25 pound in total I used control surface build which made it so easy to create to my specs. Really easy tbh if you know a little about code and midi.
the build is here-

Me getting help with the code-

Cheaper Arduino's will require Hairless midi to run but A good Teensy can run standalone Straight Usb to midi


I made a pedal with 10 stomps, 8 for CC changes and 2 to go up and down 4 banks
I also use a cheap expression pedal to act as a volume/ Wah pedal to use in TH-U

My code is here-
#include <Control_Surface.h>
HairlessMIDI_Interface stream;
CCButton But1 = { 8, 62};
CCButton But2 = { 4, 63};
CCButton But3 = { 5, 64};
CCButton But5 = { 6, 65};
CCButton But6 = { 2, 66};
CCButton But8 = { 3, 67};
CCButton But9 = { 10, 68};
CCButton But10 = { 11, 69};

Bank<4> bank;
IncrementDecrementSelector<4> selector = {bank, {7, 9}};

using CCSmartPot = Bankable::CCSmartPotentiometer<4>;

CCSmartPot potentiometer = {
{bank, BankType::CHANGE_CHANNEL}, // Bank configuration
A0, // Analog pin connected to potentiometer
{MIDI_CC::Channel_Volume, CHANNEL_1}, // Channel volume of channel 1
};

void setup() {
Control_Surface.begin();
}
void loop()
{
Control_Surface.loop();
}

great work , Thank you so much

 

Another option is loading this firmware into your arduino to allow it to be seen as a usb device.

Fyi @Plainview, I've recently found a second hand AKAI APC Mini for $30. 8 Faders and 72 illuminated buttons that can be lit in different colors using MIDI messages. Although I'm very much into Arduinos and Raspberries, I'm sure I could not build anything comparable for the price.

 

trust me If I found anything like this in my area I wouldnt have thought about the arduino stuff anyway
